CLT panels in Japan from cradle to construction site gate: global warming potential and freight costs impact of three supply options

Abstract

This study investigates the effect of three different multimodal transport combinations for cross laminated timber (CLT) supply on global warming potential and freight costs from cradle to the construction site gate. It attempts to demonstrate to what extent a local approach could be beneficial, both environmentally and economically. It was found that emissions during the transportation modules will be more than those from the manufacturing stages in the case of intercontinental routes, contrary to the environment-friendly idea usually associated with timber products. Also, the results showed that it is crucial to locate CLT manufacturing facilities as close as possible to wood supply sources, in order to reduce the freight costs of low value-added products.
